From the model, a new index named the two-dimensionality is introduced. By calculating the two-dimensionality in a case of a sample diameter of 20 mm, it is found that a combination of an InGaAs seed crystal and a BN crucible is inappropriate from the viewpoint of homogeneity. To find a more appropriate combination of a seed and a crucible materials, a dominant mechanism of two-dimensionality deterioration is discussed. By considering the dominant mechanism, it is successfully obtained of the more suitable combination., 資料番号: AA0049798004, レポート番号: JAXA-SP-05-036E}, title = {Numerical study of thermal conduction influence on homogeneity of InGaAs crystals}, year = {2006} }
